Abstract
A transmitter transmits a spread spectrum pilot and data signal. Each signal has an associated chip code. A receiver receives the transmitted pilot and data signal. The received pilot signal is filtered using the pilot chip code and weights are determined for components of the received pilot signal using an adaptive algorithm. The received data signal is weighted by the determined weights and filtered with the data signal chip code to recover data from the received data signal.
